Update:

I didn't have good luck with the AST-LC90. 10,000km and out it came.

I started noticing hard steering, poor return to centre. I checked the LBJs 2 times (they are newer OEM) and saw no issue with them. Eventually I pulled the LC90 out of the intermediate shaft and that is where the binding was occurring. The steel liner in the hole seems to be soft and the spring and hardened shaft nubs were wearing into it. Luckily I had my original in the tool box and put it back in (8,000km from home). Steering back to normal, whew.

I left the ball in, it seems OK. Not sure about the LC90, can't recommend it now.


fourfive: I don't think I have any of what you are describing. I think the wheel is pretty darn stable. I don't really think any of this would address what you describe.
